T all whom it may concern:

Be it known that I, EMrL WALDER, ject of the Emperor of Germany, residing in thecity and county of Philadelphia, State of Pennsylvania, have invented a new and use- 7 ful Bobbin-Winder, of which the following for controllin is a specification.

My present invention consists of a novel construction of a bobbin winder in which bobbins of a uniform size are produced, said .bobbins' when finished being automatically maintaining the feeding lever stationary at predetermined. times.

It further'consists of novel means actuated by the driving shaft for intermittently actuating the severing. mechanism. i

It further consists of novel means controlled by the size of the bobbin being wound 1 from themac 'ne..

1 represents a persp I It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my'invention I have shown in the accompanying drawings, one form of a device since this embodiment best illustrates the principle there- ,of and has been found inpractice to ive.

satisfactory and reliable results, althoug it is to be understood that the various instrumentalities of which my invention consists can'be variously arranged and organized and that my invention is not limited to the recise arrangement and organization of t ese instrumentalities as herein shown.

or er that it may en-' The crank' arm 24 is also provided with a recess or aperture 25 with which is adapted to engage at a desired time 'a pin or lug 26 carried y a set collar 27 adjustably secured on the shaft 19 so that during the. operation when the lug 22 engages the recess 23 the crank arm 24 will be rocked, and when the Mg 26 engages the recess 25 the crank arm 24 w' 1 el be h stationary.- The pin or lug 22. and its 006 crating recess 23 are the same as the in or ug 26 and its cooperating recess 25 w ich latter are. clearly shown in Fig. 2.

. 28 designates a feeding lever, one end of which is adjustably secured to the crank 24 by means of a set screw 29, the other end thereof being slotted. as seen at 30, thereby adapting it to retain the thread 31, as seen most clearly in Fi 1.

32 designates a raft journaled in the standards 9 and 21 and having adjustably secured 48 having an operative cam face 49 andthereon a friction disk 33 ada ted to be driven. by the friction disk 5. e shaft 32 hasadjustably secured thereto at its end by means of a set screw 34 a polygonal shaped and referably tapering needle 35, it being noted that the feeding lever 28, as most clearly seen in Fig. 2, is deflected so that the slotted end thereof reciprocates in proximity to the needle 35.

36 designates a worm mounted on the driving shaft 3 which meshes with a gear wheel 37 carried by a shaft 38 journaled in standards 39.

40 designates a clutch member mounted on the'shaft 38 which is adapted to co-act with the clutch member41 inte ral in the present instance with the cam 42 eyed on a shaft 43 journaled in the standard 21. The cam 42 is cut away on one side to form a release face 44 and a leading face 45.

46 des' nates a spring interposed between the two 0 utch members 40 and 41 and normally tending to move the member 41 out of enga ement with the member 40. The clutch members are normall held in engagement with each other by the engagement of the flange 47 with the side of a cam block fixedly. mounted on shaft 50 journaled in the standards 21 and 39. The shaft 50 is maintained in normal position by means of a torsional spring 51, one end of which is fixed to the standard 39, the other end thereof being secured to said shaft 50.

52 desi nates a set collar fastened on the shaft 50 aving a portion of its periphery cut away to form a shoulder 53, which is adapted to be stopped by the upperend of the standard 54 carried by the base 1. The set collar 52 has a flange 55 on its outer side which is cut away to form a stop 56 with which the deflected end 57 ,of a lever 58 is adapted to engage, 'said lever being pivoted intermediate its ends as at 59 to a suitable portion of the base. The opposite end of the lever 58 has pivoted thereto at 60 a lever arm 61 which is pivoted intermediate-its end, as at 62 to an extension from the standard 21. The upper end of the lever 61 is deflected as seen at 63 to form an extension, which is substantially arallel with the needle 35 and which will engage the bobbin which is being wound, as will be clearly understood from Fig. 1 of the drawing.

64 designates a crank adjustably mounted on the shaft 50 and having pivoted thereto a swivel 65 through which asses the knife ac-.

tuating rod 66, the end 0 which is threaded and provided with lock nuts-67 on one side of the swivel 65, which serve as a stop to limit the movement of the rod 66 in one direction.

68 designates lock nuts on the rod 66, between which and the swivel 65 is interposed a spring 69 whereby the rod 66 is normally maintained in its rearmost osition. The forward end of the rod 66 is pivoted at 7 0 to a knife blade 71, which is mounted on the rod 72 extending from the standard 21.

73 designates the knife blade which is adjustably mounted on the rod 72.

7 4desi nates a spring interposed between normally maintained in its forward position 1 by the tension of said spring.

76 desi nates a rod, one end of which is eccentrica ly connected at 77 to the shaft 50, the other end thereof being secured at 78 to the bracket 24, which carries the feed lever 28'. As seen in Fig. 1, the connection of the rod 76 with the shaft 50 and crank arm 24 are such that the reciprocation of the thread guide will not subject this rod to undue strain.

79 designates a spring, one end of which is suitably secured tothe base, the other end thereof being deflected and ada ted to engage with a pin or lug 80 carried y the shaft 43, at a suitable time, and prevents improper movement of the shaft 43 and its ad uncts.

81 designates a standard carried by the base 1, to which is pivoted an elbow lever 82 with the enlarged end 83 of which is ada ted to engage at a certain time a cam bloc 84- mounted on the shaft 43. The upper end of of the lever 82 is apertured or slotted, as seen at 85, and with this slot is adapted to engage a pin 86 secured to a discharge rod or arm 87, which is journaled in the standard 21' and an extension from one of the standards 2. The lever 82 and the arm 87 are maintained in their normal position b means of a spring 88, one end of which is astened to the in 86, the other end thereof being suitably astened to the standard 2. The outer end of the discharge arm 87 is deflected and apertured as seen at 89, in prder that it may be guided on the needle or bobbin spindle 35. As seen in Fig. 1, 90 designates a bobbin which has already been wound and 91 designates the bobbin which is being wound.

The operation of'my novel construction of bobbln winding machine will now' be readily understood :The driving shaft 3 is driven by any suitable type of motor or engine. Assuming that the parts are in the position seen in Figs. 1 to 3, inclusive, it will be apparent that owing to the employ' ment of the friction disks 5 and 33 that the shaft 32 which carries the bobbin spindle or needle 35, will be rotated. As the disk 5 rotates, owing to the provision of the lever the cam 42 engages 7 rock shaft 8, crank arm 10, connecting rod 13, sleeve 14 and 'vot in 15, the arm or bracket 18 to which sai pin is secured will be oscillated and since the pin 22 carried by said bracket is in engagement at this time with the recess or seat 23 of the bracket 24, said bracket 24 will be oscillated and thereby oscillate the feeding lever or arm 28 which will cause the thread, which passes through the slot 30 in the end of said lever 28, to be Wound u on the needle 35 which may be either po ygonal as seen in Fig. 1 or round as seen in Fig. 8, and which, it is to be understood, is continually rotating when the ma chine is in operation. The worm 36 on the drivin shaft 3 drives the gear on the shaft 38 an since the two clutch members 40 and 41 are at. this time in engagement with each other, the cam member 42 will be rotated. As soon, however, as the release face '44 of the side of the cam 48, said cam 42 and clutch member 41 will be moved away from and out of engagement with the clutch member 40, owing to the provision of the s ring 46. The machine is so constructed an the parts so proportioned that at this time the bobbin occupying the position of the bobbin 91, seen in Fig. 1, owi to the redetermined' size which has now een readhed, will cause the extension 63 of the member 61 to move rearwardly, thereb rocking said lever 61 and causing the de ected end 57 of the lever 5-8 to be disengaged from the stop 56 of the flange 55 and owing to the employment of the torsional sprivnlg 51 the cam block 52 and the shaft 50 'l be rotated until-the stop '53 engages with the upper end of the arm 54. Owing to the PIQVISIOI). of the crank 64 to which the connecting rod 66 is mounted, the blade 71 will be opened, the parts now assuming the osition-seen in Fig. 8.

When the c utch member 41 is out of en agement with the clutch member 40 the deflected end of the spring 79 engagin with the pin .80 carried b the shaft 43 wifl prevent said shaft and t e cam and clutch member mounted thereon from any im roper movement, as will be evident. As t e shaft 50 is partially rotated by the spring 51 the cam 49 is move into engagement-with the portion 92 formed by the'cutting away of the flange 47 of the cam member 42, so that the clutch member 41 is moved into engagement with the clutch member 40 and the shaft 43 will rotate in unison with the shaft 38. As the shaft 43 rotates the operating portion of the cam block. 84 engages the end 83 of the elbow lever '82 and causes said lever to be rocked and owing to the provision of the pin 86 and the slot 85 the discharge rod or arm 87 will be moved forwardly so that the end thereof which is loosely mounted on the spindle or bobbin support 35 will advance the bobbin, which occupies the posit-ion of the bobbin 91 and move the same into the position of the bobbin seen at 90, it being understood that there are always two bobbins on the bobbin support or spindle 35, one finished ready to be cut off, and the other being wound. As soon as the cam 84 asses out of engagement with the end 83 of the lever 82, the discharge arm 87 will be returned to its normal position owing to the provision of the spring 88, as will be evident.

I wish to call special attention to the manner in which the feeding lever 28 is maintained in a stationary position during a predetermined time. It will be seen that as the shaft 50 is rocked, thereby causing the knife blades 71 to move away from the knife blade 73, the connection 76, one end of which is secured to the crank 24, will cause said crank 24 to be moved so that the pin 22 will not ongage with the recess 23-but the stationary pin'26 will engage with the seat 25 therefor 1n the crank 24 and maintain the same in a stationary position so that the feeding lever is not reciprocated, and while the bobbin just completed is bein moved towards the end of .the spindle 35 the thread or yarn will not be wound in a spiral mannerbut will be wound straight around the bobbin so as to serveas a hinder or fastener and prevent the same being unwound after it is dischar ed from the machine. The manner in which this thread is wound around the bobbin may be readily understood from-the bobbin 90 seen in Fig. 1. The finished bobbin 90 as the discharge arm 87 is advanced will be moved outwardly and dro from the s indle 35 be tween the knife b ades 71 an 73 and the thread between the two bobbins will be severed. The knife blade 71 is moved from the position. seen in Fig. 8 to the position seen in igs. 1 and 2 and 3, res ectively, in the following manner: The leading face 45 now enga es with the cam face 49 of the block 48 an the shaft 43 continues to rotate, thereby rotating the cam 42 and the shaft 50 will be rocked rearwardly, and thus owing to the provision of the actuating rod 66 the knife lade 71 will be closed against the knife blade 73 and the completed bobbin beseparated from the contiguous bobbin, and drops into any suitable receptacle. As the rock shaft 50 returns to its normal position, the connection 76 will cause the crank 24 to be moved out of engagement with the stop 26 and into engagement with the stop 22, whereby the feeding arm 28 will be reciprocated as before, and a new bobbin will be wound upon the spindle 35. As the knife blades close, the stop 53 is moved out of engagement with" the stop. 54 and the deflected end 57' of the lever 58 is moved into engagement with the sto 56'.

' wish to call special attention to the fact that the knife blades close in a very gradual manner and. that owing to the employment of the spring 69, yieldin means are provided for actuating the knife blade 71. The lever arm 58in the present instance is provided at its outer end with a slot 93 in which if desired, the end of the lever 61 may be pivoted, thus adapting the machine for bobbins of a larger size.

It will now be apparent from the foregoingthat I have devised a novel and useful construction of a bobbin winder which embodies the features of advantage enumerated as desirable in the statement of invention and the above description. and while in the present instanceI have shown and described the preferred embodiment thereof which I have found in practice to give satisfactory and reliable results, it is to be understood that it is susceptible of modification in various particulars without departing from-the spirit and scope of the invention or sacrificing any of its advantages.
